u-connectXplorer is the official companion app for u-blox u-connectXpress wireless modules. It is built for engineers and developers evaluating, integrating, or debugging u-blox short-range modules. The app supports BLE Central (GATT Client), BLE Peripheral (GATT Server), socket terminals, MQTT, and OTA firmware update — all in one tool. SUPPORTED u-blox MODULES • NORA-W36 — Wi-Fi 4 + BLE 5.3 • NORA-B26 — BLE 6.0 • NORA-B27 — BLE 6.0 • NORA-B20 series — BLE 6.0 with DFU OTA BLUETOOTH CENTRAL • Scan with name, UUID, RSSI, and Resolvable Set Identifier filters • Full GATT browser — discover services, read, write, subscribe to notifications • GATT profile cards — Battery, Heart Rate, Device Information, Environmental Sensing, Current Time, Automation IO • MTU negotiation up to 247 bytes • Connection dashboard with live RSSI, MTU, and PHY information SERIAL CONSOLE • u-blox SPS (Serial Port Service) — credit-based flow control • Nordic UART Service (NUS) — bidirectional serial • Throughput tests with live kB/s chart (Echo, TX flood, RX, RTT) BLE PERIPHERAL (GATT SERVER) • Advertise SPS or NUS for module testing • Standard GATT profiles — Battery, Heart Rate, Environmental, Device Info, HID Keyboard, Current Time • Custom GATT service builder — define your own UUIDs and characteristics WI-FI TOOLS • Wi-Fi Provisioning over BLE (Nordic protocol) — configure modules wirelessly NETWORK & IoT TOOLS • Socket Terminal — TCP, UDP, TLS (client and server) with mutual-TLS support • TLS certificate manager — upload PEM certificates, build SecurityContext • MQTT 3.1.1 client — publish, subscribe, QoS, last will, TLS • Network diagnostics — ping with RTT chart and gateway detection, mDNS service discovery, iperf2 bandwidth test, network interface info FIRMWARE UPDATE OVER BLE • Nordic DFU OTA for nRF-based modules • SMP / mcumgr / SUIT OTA for nRF54 series (NORA-B20, B26, B27) • Firmware browser with version picker CHANNEL SOUNDING • Simulated distance demo with live chart, statistics, and CSV export • Live measurement requires an Android 16+ device with Bluetooth 6.0 hardware ADDITIONAL TOOLS • Protocol Analyzer — real-time BLE packet capture, hex + text payload, JSON/CSV export • Tracker detection — AirTag, SmartTag, Tile, Find My Device Network • BLE Chat — peer-to-peer messaging and collaborative drawing over SPS/NUS • Remote control API — JSON-RPC 2.0 WebSocket server for automation DEMOS • Dice Demo — a 3D dice mirrors a real ANNA-B5 die's motion in real time over BLE • ALMA Demo — asset tracking with the ALMA-B2 on-device NPU (drops, shakes, hits) and a map-linked event log • IMU Streamer — stream the phone's motion sensors over UDP, BLE GATT, or MQTT This app does not collect, store, or transmit any personal data. All wireless communication happens directly between your iPhone, your u-blox module, and the destinations you choose.

BLE Insight is a powerful Bluetooth Low Energy development tool designed for developers, engineers, and IoT professionals. Scan, connect, and communicate with any BLE device — all from your iPhone. Visualize every detail of BLE communication with real-time sequence diagrams, live RSSI monitoring, and interactive data graphs. KEY FEATURES • Device Scanner Discover nearby BLE devices instantly. View device names, RSSI signal strength, and detailed advertisement data including service UUIDs, manufacturer data, and TX power. • Service & Characteristic Explorer Browse all services and characteristics of connected devices. Read, write, and subscribe to characteristics with a single tap. Supports Hex, UTF-8, and Decimal data formats. • Real-Time Sequence View Watch BLE communication unfold in real time. Every connection event, service discovery, read, write, and notification is displayed in a clear, chronological timeline. • RSSI Signal Monitor Track signal strength with a live-updating chart. View current, min, max, and average RSSI values at a glance with color-coded signal quality indicators. • Data Graphing & Logging Plot numeric characteristic values on real-time graphs. Supports standard integers, floats, and IEEE 11073 FLOAT formats. Export logged data as CSV. • Automated Test Scripts Record communication sessions and convert them into reusable test scripts. Create custom test sequences manually. Run scripts and verify each step with pass/fail results. • Beacon Scanner Detect iBeacon and Eddystone beacons nearby. View UUID, Major, Minor, proximity, and signal strength for each beacon. • Favorites & Session History Star your frequently used devices for quick access. All communication sessions are automatically saved and can be reviewed or exported anytime. • Connection Parameters View MTU sizes and connection details. Configure connection options including background notifications and auto-reconnect (iOS 17+). Built for professionals who need visibility into BLE communication. Whether you're developing firmware, debugging a sensor, or testing an IoT product — BLE Insight gives you the tools to understand what's happening over the air. Requires iOS 17.0 or later. Bluetooth 4.0+ (BLE) capable device required.
